Power
In RimWorld, electricity is the key to survival. Most vital structures and buildings require power, and building an efficient power grid is the key to success.
Power generators
Solar generator
See also: Solar generator
Solar panels are a cheap first way of producing power from the limitless energy of the Sun.
The drawback is that they don't work during the night or during eclipses, requiring batteries to power lights and turrets when there is no sunlight available. Template:Clr
Geothermal generator
See also: Geothermal generator
A Geothermal generator is a very good and reliable power source drawing its energy from the heat of the planet's core. It is the only power generator which needs research to be built.
It produces a lot of power all day round but it is more expensive to build than the other power generators and it has to be placed on geothermal geysers.
Those geysers are placed at random, sometimes not even occurring at all, and are usually positioned far from the initial landing zone.
This makes geothermal generators either a valuable asset far from the safety of the core base, or necessitates a base relocation to a zone harder to defend against raiders.
| Type | Cost | Size | Power output | Day | Night | Placing |
|---|---|---|---|---|---|---|
| Solar | 80 Metal | 4x4 | 1700 W | ✓ | ✗ | In Sunlight |
| Wind Turbine | 125 Metal | 5x2 | 750 W (1125 W during snow or rain fall.) | ✓ | ✓ | In open ground. |
| Geothermal | 370 Metal | 6x6 | 3600 W | ✓ | ✓ | On geysers |
Power transfers
Power conduit
See also: Power conduit
A power conduit transmits power from generators or batteries to appliances.
It is a big cable that allows appliances to be powered up to 5 squares away from it.
A power conduit doesn't consume any power but takes some space on the floor, as most structures and buildings can't be built over it, except for solar generators, doors, walls and batteries.
Conduit Walls
See also: Wall
Regarding power distribution, a conduit wall works exactly the same way as a power conduit, also powering appliances up to 5 squares away from any powered section.
Door
See also: Door
Doors allow passage in a 1 square opening in a built wall or cave wall. It acts like a power conduit and needs a direct link to a conduit wall or to a power conduit to distribute power. This door closes and opens slower depending on the material the door is made from.

Power storage
Batteries
See also: Batteries
A battery can only hold 10,000 KJ, but it won't deplete over time if no appliance is connected to it.
If a power generators' output exceeds appliances power consumption, excess power will be distributed evenly amongst all non-full connected batteries, charging all batteries at the same rate. Likewise, if power consumption exceeds power generation, all non-empty batteries will deplete at the same rate to fill the power gap.
Appliances
Appliances are structures or buildings that require power but don't transmit it. Appliances don't require a direct power cable/wall connection, they can be placed up to 5 squares away from them. When connected to the power grid, it can take a few moments before an appliance turns on.
| Appliance | Cost | Size | Power consumption |
|---|---|---|---|
| Standing lamp | 5 Metal | 1x1 | 150 W |
| Sun lamp | 20 Metal | 1x1 | 600 W |
| Nutrient paste dispenser | 90 Metal | 4x3 | 200 W |
| Comms console | 120 Metal | 3x2 | 200 W |
| Cook stove | 80 Metal | 3x2 | 350 W |
| Auto-turret | 90 Metal | 2x2 | 250 W |
